Saw a bunch of these comments under the last Steam post:
And since actions speak louder than words, check out this cannon action (sound on)!
Basically, as you guys suggested, once you clear the area from enemies, you will now be able to partly repair the cannon and shoot with it around the area its located in.
Here's what the whole sequence looks from the inside, and the cannon animation on its own.
Hope you guys like it, and keep the feedback coming!
More island news coming soon.
P.S. Let me know what's going to be your first target in the comments. I'm probably aiming for one of my teammates
P.P.S. Volcanoids is 30% off I think
